It isn't quite saturating, but:

Also, you have to increase TCP max window size to saturate a 1Gbps link.
You need to increase tcp_rmem[2] on receiver and tcp_wmem[2] on sender.
This is easily done with sysctl. And of course you have to have enough
memory that TCP isn't deciding to throttle you for chewing too much
memory in the
